Furthermore, precise measurements of the metal abundance patterns of the ICM and IGrM are expected to offer new tests of stellar astrophysics. Elemental abundances in the Sun and in the stars in the Local Group have so far been the most commonly used points of comparison in order to check whether or not current theoretical nucleosynthesis yields provide a self-consistent picture that can appropriately describe Galactic chemical evolution [1]}, [2]}. High-resolution X-ray spectroscopy with \(XRISM\) , followed by the Athena X-IFU (see Section REF ) will provide complementary measurements of the enrichment history of the hot-diffuse gas, with a precision rivalling optical and infrared stellar spectroscopy, ushering in a new era of extra-galactic archeology.
